So, first step, let's find a pattern! There are plenty of patterns online in videos or printables, as well as books. The site I'd recommend for beginners would be Origami Club- http://en.origami-club.com/index.html . Not only is it filled with diagrams, but it has printable paper that you can use if you don't have origami paper. I'm going to show you the origami crane pattern which is one of my favorites.
